Tarzan plans to cross a gorge by swinging in an arc from a hanging vine. If his arms are capable of exerting a force of 1820 N on the rope, what is the maximum speed (in meters/second) he can tolerate at the lowest point of his swing? His mass is 83.0 kg, and the vine is 11.0 m long.

Answer 1

M*(g + V^2/R) = 1820 N
at maximum allowed rope tension.
Solve for V.
